Then there's these things at under $100 and a couple hours work. An upfitter relay controlling a massive relay might be helpful.

No worries Joe,it's detached and I open the bay door as soon as I walk in.

Still not something I would do. You will still breathe CO as you walk in and get in your truck and there will also be some in the cab of the truck. Maybe not enough to harm you in the short term but maybe not so good over time. If your garage is close enough, it maybe good to use a remote and open the garage door when you start your truck.

I have only been in temps as low as the mid to high 20’s so far but with the engine block heater plugged in for a few hours I haven’t had any concerns. The EOT starts higher/warmer than it would without the heater and seem to climb pretty fast once I start driving. I’m about 4 miles from work and drive through several red lights to get here, so no chance for running higher RPMs but the air coming from the vents are warm by the time I get here. I do have a high idle wired into one of my upfitter switches so I typically remote start the truck when I’m putting my boots on to walk out the door. I leave the high idle engaged so when it cranks the RPMs kick up to 1200, then I walk out and unplug the truck and roll the extension cord back up. So far my EOT has been around 70-80F by the time I get in the truck and get settled and pull out of the drive. Around 100F I can start feeling warm air pretty good and it doesn’t take long to get there. I just got a Banks IDash, so I’m curious to see what my ECT’s actually are too when using the engine block heater.

Adding the engine block heater is less expensive and easier than adding the supplemental heat aftermarket as far as I understand.

When it is -10F or colder, plugging your truck in for 4 hours or longer helps with starting, but not with getting heat. On my truck and my (pre pandemic) commute, I won't get anything resembling heat until I've gone 12-15 miles.

Dress warm, crank up the seat heater to TOASTY and hope for the best.

Toasty is right. With all 3 LED's turned on my heated seats will put grill marks on your butt!

Glad you posted this. I just picked up my 2022 6.7 also and I told myself I didn't need the supp heat until it took 20 min to get decent heat at -5F degrees the other morning lol

Well crud, I ordered mine w/o the supplemental heater thinking the engine block heater would suffice here in Colorado if I let the truck idle for 10-15 minutes in the morning before leaving to clear the windshield. Oh well, live & learn I guess! Good info in here, thanks for sharing y'all!

28° this morning and I did a 10-12 min warmup. Seats were fairly warm and the chill was starting to knockoff. Prolly 5 mins into driving the heat was coming in decent

High idle with the block heater makes a huge difference on heating time. Gotta love remote start and remote control outlet for the heater.
